Phil Mickelson has made a triumphant start to his PGA Tour Champions career as he tied the lowest 54-score ever to secure a wire-to-wire win at the Charles Schwab Series at Ozarks National in Missouri.
The five-time major winner carded a five-under-par 66 in the final round for a 22-under 191 total that left him four shots clear of fellow American Tim Petrovic.
"I really enjoyed playing here, I enjoyed seeing all the guys again and I enjoyed the way they were so accommodating and fun," said Mickelson.
"I really had a great time."
Hall of Famer Mickelson has won 44 events on the regular PGA Tour and qualified for the senior circuit having turned 50 in June.
"Obviously, I have a lot of work to do and some redemption at Winged Foot, but it's a great golf course and I'm looking forward to the challenge." - Phil Mickelson.
After failing to advance beyond the opening event of the PGA Tour's season-ending play-offs last week, Mickelson decided to play at Ozarks National.
He led Australia's David McKenzie by one after the first round and then led another Australian Rod Pampling and Petrovic by four on Tuesday.
Both Pampling and McKenzie could only muster one-over rounds on Wednesday and finished tied 11th and 20th respectively, 10 and 11 shots behind Mickelson.
But the five-time major champion is not yet done with the regular PGA Tour as he plans to play a warm-up tournament before teeing it up in the US Open at Winged Foot next month.
In the 2006 US Open at Winged Foot, Mickelson held a one-shot lead playing the final hole but carded a double-bogey and lost by one shot to Victorian Geoff Ogilvy.
"Obviously, I have a lot of work to do and some redemption at Winged Foot, but it's a great golf course and I'm looking forward to the challenge," he said.
